To make concrete there are four basic materials you need: 1. Portland cement - You can buy this in a 94lb bag 2. Sand - Course or Fine will work (course sand will give you a stronger mix) 3. Aggregate (stone) You can use 3/8", 1/2", or 1/5" stone for aggregate 4. Water - Clean cool water is best.
Sixty- or 80-lb. bags of concrete mix are readily available at home centers, lumberyards and hardware stores. Don't confuse concrete mix with sand mix or mortar mix. They don't contain the aggregate (stones or gravel) that's necessary to make a pour thicker than about 3/4 in. Why Use a Wheelbarrow for Mixing Concrete?
2. Aggregate Grading The particle grading of the aggregate mainly affects the quantity of mixing water required for adequate workability. Increase in the proportion of fines increases the water requirement and this leads to a lower concrete strength unless the cement content is increased.
Transporting the sand, gravel, and bagged cement requires a pickup truck with a bed that seals tight. To mix your own concrete for footings and piers, use 1 part Portland cement, 2 parts clean river sand, and 3 parts gravel (maximum of 1 inch diameter and specially washed for concrete mixing). Add clean water, a little at a time, as you mix.
Crushed gravel driveways refer to those composed of coarse sand intermixed with small stones. Typically, the bottom layer is made of a mixture of sand, dirt, and stone. The middle layer of the driveway is primarily made up of simple gray gravel, and while the top layer can also be made with gray gravel, many people choose a more decorative ...
In specific recipes, such as a 3 2 1 concrete mix or a 5000 psi concrete mix ratio, concrete sand plays a vital role in defining the concrete's compressive strength and workability. ... Fly ash, recycled glass, and crushed recycled …
When left in their natural states, crusher fines are an alternative to mulch. It can function as a pathway or patio surface when mixed with a stabilizing product, like organic psyllium binders. Similar to sand in texture, crusher fines can give a more flowing, organic appearance to your landscape by softening the appearance of hard lines.

Next, select your preferred mix ratio to get the volumes of cement and sand for a mortar mix and cement, sand, and gravel for a concrete mix. The weight of cement is also automatically calculated using a cement density of 1440 kg/m³ (90 lb/ft³) but you can change this value by entering a new one in the Cement density field of our cement ...
Concrete – A mix of gravel, sand, crushed rock, cement and water and is typically made extremely thick. Mortar – Mixture of water, sand, cement but is made much thinner than concrete and is used typically for pointing or bricklaying. Making this too thick would cause cracks. How To Mix Mortar
